I will try to resolve this problem, or will separate three metadata files outlive superblock if I cannot find a proper way. Actually, I recently wrote a patchset to unify all super block instances on one device into one sb, which makes the inodes outlive superblock eliminable. But the patchset has a problem that it cannot shrink a number of versions of namespace when unmounting all snapshots and a current time instance. If this implementation issue is avoidable, unifying per-snapshot sb instances seems an ideal way.
